Output in context · Ulsan Hyundai FC finished 2nd of 13 · a title-challenging side
1.33 tackles, blocks & interceptions per 90 — light defensive volume, with 2 clean sheets across 30 appearances. Behind a title-challenging side (2nd of 13) the side controls more games, so the defensive load is lighter — the value sits as much in composure and ball progression as in raw volume. Going forward he chipped in 1 goal and 3 assists — a useful bonus from the back.
Strengths
- Attacking threat. Chips in from deep: 0.59 goal involvements per 90, useful for a central midfielder.
- Creativity. 0.44 assists per 90 — a genuine creative outlet.
Watch points
- Game time. Only 17.9% of available minutes — needs a settled run to prove the level.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
Rated 36.6 overall — developing / rotation level. Defensively he reads as light defensive volume (1.33 tackles, blocks & interceptions per 90), with a bit more on the ball than most in the role. In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.
